摘　　要： 低频噪声污染是输变电工程建设重点关注的环境问题。基于对南通地区变电站噪声样本的频谱特性分析,研发了对低频噪声具有良好吸隔声性能的复合声屏障屏体,并应用于110 k V变电站噪声治理工程实践。声学仿真和验收监测结果表明,声屏障降噪效果明显,周围敏感建筑的声环境质量可满足相关环保标准要求。 Low-frequency noise pollution is a focus environmental issue of power transmission and transformation project. Based on analysing the spectrum characteristics of transformer substation noise in Nantong area,composite sound barriers which have good performance in sound absorption and insulation were producted and also finded application in noise control engineering of 110 kV substation. The result of acoustic simulation and acceptance check monitoring suggested that sound barriers had obvious effect on noise reduction. Acoustic environmental quality of surrounding sensitive buildings could meet the requirements of relevant environmental standards.
